If you actually look at it you'll see its a not printed anything like an Apple keyboard, the letters are offset for one, they are centered on Apple keyboards, and has Windows keys.
However, that’s barely relevant. They built a prototype, probably with some cheap keyboard they either had around or just quickly ordered online. The particular keyboard used for this particular prototype is literally of no relevance at all. It doesn’t even have anything to do with what they want to show.
I really don’t get this whole fucking discussion. It’s some of the most stupid stereotype pattern matching that I have every seen on HN.
